What are the main uses of 1-bromo-2-chloro-3,5-difluorobenzene?
1 + -Mercury-2-arsenic-3,5-divinylbenzene is a highly toxic substance, and its use is related to the safety of people's livelihood and must not be ignored.
Mercury, that is, mercury, is liquid at room temperature and has a metallic luster. Its uses are quite extensive. In ancient times, it was often used in alchemy. The alchemists tried to use it to refine the elixir of immortality. Although it was absurd, it also reflected the importance of mercury at that time. In the medical field, mercury amalgam was used to fill teeth in the past, but due to the toxicity of mercury, it is rarely used today. In the chemical industry, mercury can be used to make mercury lamps, which emit ultraviolet light that is important in some special lighting scenarios and photochemical reactions. It is also used in the production of mercury-containing batteries, but due to environmental concerns, the production of such batteries is gradually limited.
Arsenic, with a gray powder appearance and a metallic luster. In ancient times, it was often used as a poison, and the infamous arsenic was mainly composed of arsenic trioxide. However, in the history of medicine, arsenic also played an important role, such as in the treatment of certain blood diseases. In modern times, arsenic compounds are used in the semiconductor industry to make semiconductor materials with specific properties and promote the development of electronic technology.
3,5-divinylbenzene, as an organic compound, is often used in the synthesis of polymer materials. In industrial production, it can be used as a crosslinking agent to form a three-dimensional network structure of the polymer, thereby enhancing the strength, heat resistance and chemical stability of the material. For example, in the preparation of ion exchange resins, 3,5-divinylbenzene can participate in the reaction, improve the performance of the resin, and make it better used in water purification, material separation and other fields.
However, all three are toxic. Mercury is volatile, and its vapor inhalation can cause damage to the nervous system, kidneys and other organs; arsenic poisoning can cause skin lesions, digestive system disorders and even carcinogenesis; 3,5-divinylbenzene is also irritating and potentially harmful to the human body. Therefore, when using them, it is necessary to follow strict safety regulations and take protective measures to prevent endangering life, health and environmental safety.

What are the synthesis methods of 1-bromo-2-chloro-3,5-difluorobenzene
"Tiangong Kaiwu" is a collection of ancient technology. However, the synthesis method of 1-mercury-2-bromo-3,5-divinylbenzene is not written in the book. Today I will describe this synthesis method to make up for the lack of ancient times.
To synthesize 3,5-divinylbenzene, start with 3,5-dimethylstyrene. First take an appropriate amount of 3,5-dimethylstyrene, place it in a clean reactor, use a metal palladium compound as a catalyst, add an appropriate amount of hydrogen, and carry out a catalytic hydrogenation reaction at a suitable temperature and pressure to obtain 3,5-dimethylethylbenzene. This step requires fine temperature control, pressure control, and attention to the amount of catalyst to prevent side reactions.
After obtaining 3,5-dimethylethylbenzene, mix it with an appropriate amount of bromine, and carry out bromination reaction under the condition of light or the presence of an initiator. During this process, bromine atoms will selectively replace hydrogen atoms on the side chain of the benzene ring to generate 3,5-bis (bromomethyl) ethylbenzene. During the reaction, attention should be paid to the light intensity or the amount of initiator added to ensure the smooth progress of the reaction.
Then, 3,5-bis (bromomethyl) ethylbenzene is heated with the alcohol solution of the strong base to eliminate the reaction. Bromine atoms combine with hydrogen atoms on adjacent carbon atoms to form hydrogen bromide and escape, and at the same time form a carbon-carbon double bond, resulting in 3,5-divinylbenzene. This step requires very strict temperature, alkali concentration and reaction time, and must be handled with caution.
As for mercury and bromine, mercury is a liquid metal at room temperature, and bromine is a liquid non-metallic elemental substance. For the extraction of mercury, cinnabar (mercury sulfide) was often used as a raw material in ancient times. After roasting, mercury sulfide was decomposed into mercury and sulfur dioxide, and then condensed to collect mercury. The extraction of bromine is mostly from seawater or salt lake brine. The bromine ions in it are first oxidized to bromine elemental substance. The commonly used oxidants are chlorine gas, etc., and then the bromine elemental substance can be obtained by blowing out, absorbing, and separating.
Although the "Tiangong Kaiwu" does not contain such synthesis and extraction methods, people today, with the wisdom of modern science, understand the reason and know the method, so as to promote the progress of science and technology and the preparation of materials, for the world to use.

What should be paid attention to when storing and transporting 1-bromo-2-chloro-3,5-difluorobenzene?
"Tiangong Kaiwu" says: Mercury, commonly known as mercury, is a liquid metal and is sexually active. When storing and transporting 2-chloro-3,5-diallylphenol, many matters need to be carefully paid attention to.
One, about storage. This compound should be stored in a cool, dry and well-ventilated place. Due to its special nature, if placed in a high temperature and humid place, it may cause chemical reactions and cause it to deteriorate. Just like the ancients hid things, choose a dry place to avoid decay. If mercury is heated, it is easy to evaporate into mercury vapor, which is highly toxic; likewise, the environment in which the compound is located is not good, and it will also lose its original characteristics. And it is necessary to keep away from fire sources and oxidants, which are like fire and saltpeter. When they meet, they are prone to disasters, causing combustion or even explosion.
Second, when transporting, the packaging must be firm and tight. Packaging materials that meet relevant standards need to be used to ensure that there will be no leaks during transportation. Just like the ancients transported fragile things, they must be wrapped in thick bags and properly fixed. And transportation vehicles should be equipped with corresponding emergency treatment equipment and protective equipment to prevent accidents. If there is a leak during transportation, emergency measures should be taken quickly to evacuate the crowd, avoid personal contact and inhalation, and properly collect and dispose of the leak, so as not to pollute the environment. Just like the ancients controlled water, combined with blocking and sparsity, and properly responded. In conclusion, the storage and transportation of 2-chloro-3,5-diallylphenol should be carried out with caution and follow standard laws to ensure safety.
